“The proof that CO2
does not drive climate
is shown by
previous glaciations."
"The Ordovician-Silurian
(450 to 420 million years ago)
and Jurassic-Cretaceous
(151 to 132 million years ago)
glaciations occurred when
the atmospheric CO2 content
was more than 4,000 ppmv
and about 2,000 parts per million
by volume (ppmv) respectively."
"The Carboniferous-Permian glaciation
(360 to 260 million years ago)
had a CO2 content of about 400ppmv."
"If the popular catastrophist view
is accepted, then there should have
been a runaway greenhouse (warming)
when CO2 was more than 4,000 ppmv."
"Instead there was glaciation."
"Clearly a high atmospheric CO2
does not drive global warming
and there is no correlation
between global temperature
and atmospheric CO2."
"This has never been explained
by those who argue that
human additions of CO2
to the atmosphere
will produce global warming.”
